Television comedy has always had a unique power: unlike theatre, where performances exist in the moment, or cinema, where everything is controlled and edited to perfection, the best television comedy seems to arrive unexpectedly — a response that goes too far, a line that lands harder than anyone intended, a scene that takes a perfectly logical left turn into something unforgettable. These fifteen moments are ones that, wherever you first watched them, you almost certainly discussed with someone the next morning.
1. Fawlty Towers — "Don't Mention the War" (1975)
The episode that consistently tops every "greatest British comedy" poll ever conducted, and for good reason. Basil Fawlty's increasingly frantic attempts to prevent himself — and failing — from mentioning Germany, Germany, the war, or Adolf Hitler to a group of German hotel guests remain as perfectly constructed today as they were fifty years ago. The goose-stepping sequence, improvised in part by John Cleese on set, still provokes astonished laughter from audiences watching it for the first time. The BBC has twice listed it among the hundred greatest British television programmes ever made.
2. The Office (UK) — David Brent's Dance (2001)
Ricky Gervais has confirmed in multiple interviews that the entire dance sequence in the second series of The Office was improvised; the production crew and cast members audibly breaking character in the background footage is genuine. The genius of the moment lies in how deeply uncomfortable it is — the dance is performed with sincere confidence, and that sincerity is what makes it so extraordinarily painful and funny simultaneously. It remains one of the most-cited examples of cringe comedy in British television history.
3. Friends — "Smelly Cat" Recording Session (1996)
What began as a running joke about Phoebe Buffay's cheerfully unlistenable songwriting became, in one episode, a fully produced music video set in a professional recording studio, featuring professional musicians and a polished final product that was anything but polished. The gap between the lavish production values and the song itself is the joke, and it lands completely. Twenty years later, "Smelly Cat" remains the only thing most people can tell you about the recording industry from a 1990s sitcom.
4. Blackadder Goes Forth — "I Have a Plan" (1989)
Every episode of the fourth series of Blackadder is essentially a masterpiece of escalating absurdism — Edmund's schemes to avoid going over the top into the First World War trenches become progressively more elaborate and increasingly useless. The recurring "I have a cunning plan" exchange between Edmund and Baldrick eventually transcended the show entirely, becoming a widely used idiom in British English for any plan that is technically a plan but practically useless. The quiet devastation of the final scene remains one of the most tonally perfect endings in the history of British television.
5. The IT Crowd — "Did You Turn It Off and On Again?" (2006)
The IT Crowd built its entire premise on the exasperation of technical support professionals dealing with non-technical users, and this running joke — Moss and Roy's weary default question to every caller — was milked across four series with a precision that suggests the writers genuinely understood IT support culture. The scene in which the question is asked with increasing incredulity, and the caller's revelation that no, they had not tried this, remains a perfect encapsulation of a very specific kind of professional despair.
6. Parks and Recreation — Ron Swanson's Breakfast (2013)
Nick Offerman's portrayal of Ron Swanson had been building to the "All the bacon and eggs you have" scene for four series. When Ron sits at a diner counter, stares the server down, and delivers his order with the certainty of a man who has given this extensive philosophical consideration, the moment pays off four years of character development in under thirty seconds. The waitress's dawning realisation that he is entirely serious is the scene's pivot, and Offerman's complete lack of irony delivers the rest.
7. Saturday Night Live — Celebrity Jeopardy (1996–2009)
Will Ferrell's portrayal of Alex Trebek, presiding over a game show populated by celebrity contestants of escalating stupidity, ran for over a decade precisely because its formula was so flexible. The joke is ostensibly about celebrity intelligence, but the real target is always Trebek's barely-suppressed fury, and Ferrell's ability to convey barely-suppressed fury while keeping a professional veneer is extraordinarily precise comedy acting. The running gag in which the final Jeopardy categories become increasingly surreal — "Things That Are Not the Number 5" — never stopped escalating.
8. Brooklyn Nine-Nine — Jake's "Cool Cool Cool" (2013–2021)
Andy Samberg built an entire character arc around one ad-libbed reaction. Jake Peralta's habit of repeating "cool, cool, cool" in response to uncomfortable information — first used as a throwaway line in the pilot — evolved into a signature character tell, a signal of escalating denial, and eventually the punchline of an extended running gag across eight series. The scene in which the phrase is used without its usual irony is the one most often cited by the show's writers as their favourite moment in the entire run.
9. Peep Show — The Dog Scene (2007)
Peep Show's unique first-person camera perspective made discomfort visceral in a way few sitcoms have managed. The dinner party episode of Series Four, in which Mark and Jeremy's catastrophic attempts to impress guests spiral through a series of incidents culminating in the improvised disposal of a deceased dog inside a roast chicken, is widely regarded as one of the most memorably uncomfortable twenty-five minutes in British television. The laughter it provokes is very much of the "I can't believe this is happening" variety.
10. The Graham Norton Show — Red Chair Segments (2007–present)
The conceit is simple: a member of the audience tells a story to Graham Norton and his celebrity guests; if the story is deemed insufficiently entertaining, the chair is tipped backwards mid-anecdote. The celebrity guests' visible struggle to maintain composure — particularly when a story is clearly going to end in a tipping — has become one of the most reliably funny recurring segments in British chat show history. The moments when the celebrity guests collapse before the chair is even pulled are the ones that get clipped most frequently.
11. Arrested Development — "Her?" (2003–2006, 2013, 2018–2019)
The entire premise of George Michael Bluth's girlfriend Ann — sweet, pleasant, largely invisible, consistently overlooked by every other character — was a throwaway joke that the writers realised, several episodes in, had structural potential. The running gag of family members reacting to the mention of Ann with a blank "Her?" built momentum for two series before paying off in ways that implicated the season's entire plot. It is perhaps the most technically accomplished deployment of a sustained running joke in American sitcom history.
12. Fleabag — "This Is a Love Story" (2019)
Phoebe Waller-Bridge's final series of Fleabag begins with the protagonist turning to camera — a device used throughout both series — and saying "This is a love story." The statement recontextualises everything that follows and, on second viewing, everything that preceded it. When the fourth wall breaks for the last time in the series finale, and the priest — played by Andrew Scott — acknowledges it directly, the comedy and the tragedy collapse into each other completely. The moment was cited by multiple critics as the best scene on British television in the decade.
13. It's Always Sunny in Philadelphia — "Day Man" (2007)
Charlie Kelly's musical composition, created mid-episode in an act of defiant creative inspiration, was performed with such commitment — and such specific musical weirdness — that it became a genuine fan favourite. The show's production team later staged a live concert performance of "Day Man" and the associated "Night Man" opera from an earlier episode. That a five-minute song written as a throwaway joke in a 2007 cable comedy eventually became a live concert staple is perhaps the most reliable indicator of what made Always Sunny extraordinary.
14. Succession — "L to the OG" (2018)
Matthew Macfadyen's Tom Wambsgans rapping a birthday tribute to Siobhan Roy at her birthday party — delivered with total sincerity, in front of her appalled family, performing original lyrics that are simultaneously earnest and catastrophic — is the scene that fully established Tom as one of the great comic creations in prestige television. The moment works because it is both completely character-consistent and utterly unexpected. Macfadyen performed multiple takes; the version that aired is reportedly not the most extreme.
15. Your Turn
Television comedy is at its best when it creates shared reference points — moments that, whether you watched them on broadcast, on a DVD box set, or in a late-night YouTube rabbit hole, immediately communicate something about what you find funny and why. These fifteen are a starting point. What are yours? Share your favourite TV moments in the comments below — the more obscure and specific, the better.
